Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB), Electron Beam Powder Bed Fusion (PBF-EB) or Directed Energy Deposition (DED) Systems 


MetcoAdd™ 316L is a family of austenitic steel powders with chemistry similar to EN 1.4404 and UNS S316603.


Room temperature static properties of PBF-LB processed, as-built, material coupons have been shown to be comparable to those of AMS 5424. 


For reference purposes Oerlikon has processed MetcoAdd 316L-A using fixed parameters and 40 μm layer thickness to provide data below. Additional testing has been performed by an extensive network of consortia and customer partners on a broader range of machine types. Properties may be optimized based on application specific requirements.

This material data has been provided by Oerlikon Metco.

All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
